SPECIFICATION forming part of Letters Patent No. 290,572, dated December 18, 1883.

Application filed August 7, 1883.

.To all whom, it may concern:

Be it known that I, GOODMAN, of the city of St. Louis, in the State of Missouri, have invented a certain neav and useful Improvement in Pulleys, oi' which the following is afull, clear, and exact description, yrei`- erence being had to the accompanying drawings, forming part of this specification.

Reference is made to the claims for statement of invention.

Figure l is a side view of the pulley. Fig. 2 is a section of same at 2 2, Fig. 1. Fig. 8 is an inside view of the pulley-band, a part being broken out. Fig. 4 is an axial section, showing a modiiication; and Fig. 5 is a similar section, showing a narrow pulley at 5 5, Fig. 6. Fig. 6 is a detail side view. Fig. 7 is a detail sect-ion at 7 7, Fig. S. Fig. 8 is a section at S S, Fig. 7. Fig. 9 is adetail section `at 9 9, Fig. l0; and Fig. 10 is a section at 10 l0, Fig. 9.

lIhe pulley, as shown in Figs. l, 2, and 3, will be first described.

A is a cast-iron hub, having a central annular flange, B, decreasing in thickness outwardly.

I) are a number of bracingdingers, projecting outward, forming braces to the disks G, that take the place oi' spokes or arms connecting the hub to the band I). These disks have a central orificeiitting the ends of the hub, and are formed to fit the hub and its flange B at the center. The disks are connected to the flange by bolts or rivets E. I prefer bolts'to and fitting closely the sides of the disks G.

I are bolts or rivets, passing through a pair of the lugs and through the disks between them. All of the lugs maybe thus connected to the disks, or only one or more pairs, the lugs giving the necessary lateral bracing Without such connection, while the connection in (No model.)

one place insures that the band of the pulley shall not turn on the disks:

In the manufacture the band may be finished in one straight piece, (see Fig. 3,) and by application to the periphery of the disks (the same being exactly circular) will take a circular form, and will be supported in that form by contact with the disk all around, even if made of very thin sheet.

In Figs. 4 and 5 the pulleyhasasingleplane disk, confined between the perpendicular sides of a fixed ilange, B, and collar B by bolts E, that pass through the disk C. The connection of the disk and rim or band D is similar to that described in connection with Figs. l and 2. The two parts B B in Fig. 4 are about similar in foi-in, taken together, to the single iiange B of Figs. l and 2. In Fig. 5 the connection between the hub and the disk is precisely similar to that described in connection with Fig. 4; but the connection between the disk C and band is different. In this a number of rivets, H', are fixed in the band, with their heads projecting inwardly. The heads, except one, are notched through to receive the edge of the disk, the disk being recessed to iit the unnotched head for the purpose of preventing the band turning on the disk,while allowing the band to be dra-wn tight by the clamping device. The unnotched rivet is shown in Figs. 6, 7, and S, and the notched rivets in Figs. 5, 6, 9, and 10. The ends of the band are shown secured in the manner be fore described.

I claiml. In a pulley, the combination of a suitable hub, a disk, O, and a band provided with projections to embrace the edge of the disk, and clamping device F G, to draw the ends of the band together and hold it to the disk, as set forth. ,t

2. In a pulley, the combination of a hub, a disk surrounding the hub, a baud having projections embracing the edge of the disk, and angle-lugs F, secured to the ends of the band, and bolts G to connect the band ends together, as set forth.

3. In a pulley, the combination of a hub, a disk, C, surrounding said hub, having anote-h in its edge, a band having projections to embrace the edge ofthe disk, and a proiection to IOO band having projections to embrace the edges of the disks, and angle-lugs and bolts to secure the ends of the band together, as set forth.
